To all whom Iil? may concern:

Be it known that I, LEVI DAVlS, Jr., of Alton, Illinois, have made a new andnseful Improvement in Car-Couplings, ot1 which the following is a full, clear, and exact description, reference being had to the annexeddrawings, making part of this specification, in which- Figure l is a front elevation of improved draw-bar in position; Fig. 2,a plan; Fig. 3, a side elevation of one ot' the draw-bars, the pin being down; Fig. 4, a side elevation, showing the pin drawn up', Figs. 5 and 6, details, being respectively a side elevation and a plan, showing the joined inner ends of the levers used in operating the coupling-pin; Fig. 7, a front elevation of one of' the draw-bars, showing the link upheld; Fig. 8, a vertical longitudinal section taken through the coupling on the line 8 S of Fig. 7, the weights being down and the link upheld; Fig. 9, a section similar to that of Fig. 8 the weights being raised; Fig. 10, a section taken on the line 1U 10 ot' Fig. '7; Fig. l1, a section taken on the line l1).

The saine letters denote the same parts.

The present invention relates to the means for upholding the link in the draw-bar, to the means for operating and supporting the coupling-pin, to the mode ot' operating the pinsupport, and to other minor details.

A, Figs. S, 9, represents the improved coupling.

The draw-bars B B are of the usual description, saving as modified by the present improvement.

C represents the coupling-link, and D D the coupling-pins.

Pivoted at e in each of the draw-bars is an arm, E, the arm consisting ofthe side bars, e e', united at their outer ends by a cross-bar, e2. The draw-bar is chambered ont at e3 el'to receive and provide for the working ot' the arm E. When the outer end of the arm is depressed, asin Fig. 9, the crossbar e2 is held in an offset at the outer edge ofthe lower lip, a, ot' the draw-bar, forming, in effect, part ot' the lip, and the inner ends, e5, extend upward in the chambers e4, substantially as shown.

F F represent levers pivoted at their inner ends,f, in the draw-bar, at their outer ends, j", weight-ed, and at f2 bearing upon the inner ends ofthe bars e', the bearings f2 being shaped to turn upon the bar ends. These weighted levers F F act,when free, to depress the inner ends ot' the bars e, and thereby to elevate the cross-bare?. The erossbar, as it rises, encounters the link G and supportsit in a horizontal position. The outer ends,f, of the levers F, when down, rest upon or come over the link C, and co-operate with the crossbar 62 in upholding the. link.

,The levers F F are lifted by means of connections attached to the weighted endsf, and preferably as follows: A rod, G, extends from the lever upward through an opening in the top a ofthe draw-bar, and from the upperend ,of the rod a chain,G,extends,and isattaehe'dV to the coupling-pin D. Then when the coupling-pin is drawnv up, as in coupling, the outer ends ot' the levers F are drawn up with it, and the arm E moves to bringl the cross-barezinto the ot'tset in the lower lip, a, of' the draw-bar.

The coupling-pin, when upllt'ted, is sup-- ported by the device H. This feature of the construction is shown more distinctly in Figs. l1, 14, 16. It is pivoted at 7L (inline with the coupling-pin) to the draw-bar, and extends thence downward, curving around, and at its lower end pointing toward the mouth otI the ldraw-bar, and when the coupling-pin is sufficiently elevated the point h' of the part H comes beneath and supports the coupling-pin, as seen in Fig. 10.

In effecting the coupling the link C, as i passes into the draw-bar, encounters a triplever, I, which is pivoted at iin the draw-bar, and weighted at i to cause the upper end, i2,

when free, to move toward the mouth of thel draw-bar, as in Fig. 10. The link entering the draw-bar pushes the upper end, 122, Ot' the trip backward in the draw-bar, causing the end 2 to strike a part, h2, which at h3 is pivoted to the support H. The lower end, h4, of the part h2., by reason of the shoulder h5 coming` against the support H, cannot move backward, and in consequence the main support IOC lI is turned on its hearing h, and its point h' dislodged from beneath the pin, whereupon the pm falls, passing downward through the conplinglink and coupling it, and bringing the parts into the position shown in Figs. 7,11, 15, lor the dropping of the couplingpin enables the weighted levers F F to drop and act upon the arin E, and cause the outer end thereof to risc and support the link.

Then the coupling-pin is drawnV upward and the link withdrawn from the draw-bar the end i2 of the trip-lever I moves forward again. As the end i2 strikes the part h2 the latter `yields and turns upon its pivot h3, allowing the end i" to pass it and to fall into the position shown in Fig. 10. The levers F are also raised, andthe arm E assumes the position shown in Fig. 9, and the point h' of the support H falls beneath and supports the coupling-pin. The support H being pivoted on a line with the center ot' the couplingpin,the strain, when the pin is being upheld, is directly downward in line with the pin, and the point ofthe support is not liable to be accidentally di-placed from beneath the pin. The trip-lever I, heilig weighted, falls forward, as shown, when the link is removed t'rorn the draw-bar, and when the link is inserted in the draw-bar the trip-lever can be turned backward suticiently to allow the inner end ot' the link to pass in practice about two and a halt` inches beyond the pin-hole.

L L' represent levers for operating the coupling-pin. They are pivoted to the car M atm m', respectively, and are extended and arranged substantially as shown in Figs. 1, 2, the levers extending respectively from the sides of the car, and at their innerends engaging, as shown more distinctly in Figs. 5, 6, one lever, L', being forked at l', and lheother'lever, L, having the e \e. l, which engages in the fork. A pin, N, is held in the lever L', passing through the eye l, serving partly to keep the levers L L in engagement, and also to connect the levers 3, 4, the pin passing loosely through a hor1- zontally-elongated eye, d, in the top ofthe pin. By moving the levers L L,which, as seen,can be done from either side of the car, the coup vers L L can be fastened by means ot' a pin, l2, and chain L3, the pin l2 being inserted in suitable holes, l, in car, according to the position ofthe levers. The eye d is elongated to pro- I claim- 1. In a car-coupling, the combination of the link C and the pivoted arm E, for the purpose described.
